[Mono-dev] Setting and Getting Thread Priority
After adding support for setting and getting thread priorities I’ve found there’s one piece missing. Before a thread is started you can set its priority such that when it’s started it will start with this priority instead of the priority of the thread creating it. At the moment the code lets this happen but does nothing with it. I have started adding code to fix this missing piece. The trouble I am having is that the wthreads.c implementation of GetThreadPriority() will simply return THREAD_PRIORITY_NORMAL if the thread hasn’t been started yet: even if a call to SetPriority has already been made. I was storing the priority value in the MonoThread structure, however, wthreads.c does not have visibility of this structure. I thought of putting it in MonoThreadInfo but I’m not sure at which point this structure comes into existence. The other place is within MonoThreadInternal which wthreads.c does see but this requires a change in Threads.cs which has a one-to-one field correspondence with the structure. The other changes work fine such that a thread (running with the right policy) will have its priority set at creation time. All that is missing is GetPriority reporting the correct value before start time.

Re: [Mono-dev] Loader Optimization with mono
AFAIR, multiple app-domains share things inside the same process. It's like, for example, in ASP.NET where there are multiple web sites running in the same web server (thus a single mono/.NET VM instance). If you use web farming, or as is typical in ASP.NET Core start separate VMs for each web app, there won't have any sharing of jitted code. WIth multiple AppDomains in the same process, common code will be jitted once and shared by all the applications, but beware that different versions of core libraries will jit to different executable code, meaning possible duplication of generated code. As far as you spin multiple VMs these don't share code, for many reasons, security ones being the top ranked. Rafael Teixeira O..:.)

Re: [Mono-dev] Loader Optimization with mono
What is meaning of below query http://www.mono-project.com/docs/faq/technical/ Can Mono or .NET share system classes (loaded from mscore.dll and other libs) or will it behave like Sun’s Java VM? What you can do with mono is to load different applications in their own application domain: this is a feature of the CLR that allows sandboxing applications inside a single process space. This is usually exploited to compartmentalize different parts of the same app, but it can also be effectively used to reduce the startup and memory overhead. Using different appdomains the runtime representation of types and methods is shared across applications. what is the use of below option from mono. mono --list-opt shared Emit per-domain code sched Instruction scheduling On Sat, Jun 4, 2016 at 1:29 AM, Rodrigo Kumpera wrote: > Mono doesn't implement LoaderOptimization. > > On Thu, Jun 2, 2016 at 5:59 AM, techi eth wrote: > >> Does [LoaderOptimization(LoaderOptimization.MultiDomainHost)] work as >> desired on mono? >> >> I am using Mono 4.2 version on ubuntu to test. >> >> >> >> I had following observation >> >> >> >> 1.
